It’s a well known pic, and there are others including a nice side view (http://www.google.co.uk/imgres?imgurl=http://www.woolleyfamily.co.uk/Vixen_F105_.jpg&imgrefurl=http://www.woolleyfamily.co.uk/Victorious2.htm&usg=__tUz1HFhymAUGhI9bYamXxD37dio=&h=716&w=950&sz=64&hl=en&start=16&zoom=1&tbnid=IbSd2G69WB-LzM:&tbnh=112&tbnw=148&ei=GExUUIOoK8Kw0AXvsYCoDA&prev=/search%3Fq%3Df-105%2Brefuelling%26um%3D1%26hl%3Den%26safe%3Doff%26sa%3DN%26rlz%3D1G1ACAW_ENUK473%26tbm%3Disch&um=1&itbs=1).
Appears in most books on the Vixen, the most comprehensive (Tony Buttler/Air Britain) caption to the side view picture says,

“On the 5th of October 1963 Sea Vixens from No.893 Squadron, operating near Singapore, flight refuelled two USAF F-105D Thunderchiefs from the 18th Fighter Wing, which were taking part in exercise ‘Joss Stick’. Rendezvous was made using Bukit Gombak radar and this operation allowed the F-105s to fly direct to Clark AFB in the Philippines without having to refuel over Saigon in difficult weather conditions. one F-105D, 62-4217, is seen here about to take fuel from ‘461’ XN652 in a photograph taken by Lt Mark Thomson using the port side PR camera pod on Sea Vixen FAW.Mk.1 XN654.”

Further text states the Thunderchiefs were part of 64th Tactical Wing en route from Singapore to Okinawa (and Vietnam), only one of the F-105s managed to ‘plug in’.

It must have been times like that, that TAC were glad that they specified both probe/drogue, and boom/recepticle type refuelling points, the F-105 more usually receiving fuel from KC-135s via its upper nose point.
